Moldflow, a US-listed company, specializes in injection molding CAE software and consulting companies. Since the release of the world's first mobile analysis software in 1976, it has dominated the plastic molding CAE software market. In recent years, it has been widely used in the fields of automobiles, home appliances, electronic communications, chemicals and daily necessities.
Using CAE technology, the analogy analysis of the entire injection molding process can be performed on the computer before the mold processing, accurately predicting the filling, holding pressure, cooling of the melt, and the stress distribution, molecular and fiber orientation distribution, and product shrinkage in the product. And warpage deformation, etc., so that the designer can find the problem as soon as possible, and modify the part and mold design in time, instead of waiting for the mold to be repaired. This is not only a breakthrough in the traditional mold design method, but also has significant technical and economic significance for reducing or even avoiding mold scrapping, improving product quality and reducing costs.
Plastic molds are designed not only with CAD technology, but also with CAE technology. This is an inevitable trend of development. Injection molding is divided into two phases, the development/design phase (including product design, mold design and mold manufacturing) and the production phase (including purchase of materials, tryouts and molding). The traditional injection molding method is that before the formal production, because the designer designs the mold by experience and intuition, after the mold is assembled, it usually takes several trials. After the problem is found, it is not only necessary to reset the process parameters, but also need to modify the plastic products and Mold design, this will inevitably increase production costs and extend the product development cycle. CAE technology can completely replace the test mode. CAE technology provides a complete solution from product design to production. Before the mold is manufactured, predict the entire molding process of the plastic melt in the cavity, help to identify potential problems, effectively Prevent problems from occurring, greatly shorten the development cycle and reduce production costs.
In recent years, CAE technology has become increasingly important in the field of injection molding, and CAE technology can fully solve the problems in the injection molding process.
The inevitable trend of CAE technology plastic mold design development
Mold is an important process equipment for the production of various industrial products. With the rapid development of the plastics industry and the promotion and application of plastic products in the aviation, aerospace, electronics, machinery, shipbuilding and automotive industries, the demand for molds is increasing. High, traditional mold design methods have been unable to adapt to product replacement and quality requirements. Computer-aided engineering (CAE) technology has become the most effective way to penetrate these weak points in plastic product development, mold design and product processing. Compared with the traditional mold design, CAE technology has great advantages in terms of improving productivity, ensuring product quality, reducing cost and reducing labor intensity.
